Alredy cleared, but keep showing again. The firmware is ver.1.40 updated about 1 or 2 mnth ago not sure exactly,rigth after updated I plug in the AR2412 and its automaticcally updated too, with the message that says updating succesfull. On my though updating only once with one vers, and its confirm succes. But why the message keep showing(the QOS error), so i think it’s something else go wrong. Last sunday service running 2 hrs and that message showed 2 times and 2 times cleared.
